Abstract (en)
[origin: WO2007003362A1] This invention relates to a method for controlling the consumption limit date of a digital content which is transferred from distribution means (100) to a consuming device (120) during a temporary connection to be consumed on that device until the limit date, the distribution means (100) having a clock (104), called a reference clock, the value of which at each instant is called the true date. According to this invention, each time the consuming device connects to the distribution means (100), a signal including the true date is transmitted from the distribution means (100) to the consuming device (120) by a secured method to verify that the consumption limit date is not exceeded.
